Summary:
The present work aims to evaluate the impact of 200 MeV proton irradiation on Time-Dependent Dielectric Breakdown in SiC MOSFETs using Constant Voltage Stress (CVS) measurements. After proton irradiation, commercial SiC MOSFET devices were classified based on the occurrence of catastrophic Single-Event Burnout (SEB). Constant Voltage Stress (CVS) measurements were then employed to evaluate the Time-Dependent Dielectric Breakdown (TDDB) characteristics of the surviving population. A comparison between the electrical behavior of radiation-induced failures and TDDB of irradiated but survived devices, is proposed.
